[0002] With the rapid development of the environmental protection industry, various low-cost and low-energy sludge treatment equipment have emerged. Among them, vertical ultra-high pressure sludge pressing equipment is a commonly used equipment. The sludge is laid on the plate chain conveyor belt, and the plate chain conveyor belt is used to spread and convey the sludge, and then it is pressed by the sludge forming roller located above the plate chain conveyor belt to form a mud cake.
